The problem
Excessive enlargement of the wheel cylinder pilot hole in the rear brake backing plate could allow the wheel cylinder to rotate and cause loss of brake fluid. Consequence of defect: a loss of brake fluid leads to loss of rear brake action, creating the potential for an accident. Front brakes would remain operational.
The fix
Add a part to prevent wheel cylinder from rotating.
